Effects of disorder on the transmission of nodal fermions through a d-wave superconductor
J. K. Asboth, A. R. Akhmerov, M. V. Medvedyeva +1
The bulk microwave conductivity of a dirty d-wave superconductor is known to depend sensitively on the range of the disorder potential: long-range scattering enhances the conductiv…
Piezoconductivity of gated suspended graphene
M. V. Medvedyeva, Ya. M. Blanter
We investigate the conductivity of graphene sheet deformed over a gate. The effect of the deformation on the conductivity is twofold: The lattice distortion can be represented as p…
Effective mass and tricritical point for lattice fermions localized by a random mass
M. V. Medvedyeva, J. Tworzydło, C. W. J. Beenakker
This is a numerical study of quasiparticle localization in symmetry class \textit{BD} (realized, for example, in chiral \textit{p}-wave superconductors), by means of a staggered-fe…
Absence of a metallic phase in charge-neutral graphene with a random gap
J. H. Bardarson, M. V. Medvedyeva, J. Tworzydlo +2
It is known that fluctuations in the electrostatic potential allow for metallic conduction (nonzero conductivity in the limit of an infinite system) if the carriers form a single s…
Majorana bound states without vortices in topological superconductors with electrostatic defects
M. Wimmer, A. R. Akhmerov, M. V. Medvedyeva +2
Vortices in two-dimensional superconductors with broken time-reversal and spin-rotation symmetry can bind states at zero excitation energy. These socalled Majorana bound states tra…
